Sanjaya said, "During the progress, O king, of that fierce battle fraught with the slaughter of great heroes, Sakuni the glorious son of Suvala, rushed against the Pandavas. And so also, O monarch, Hridika's son of the Satwata race, that slayer of hostile heroes, rushed in that battle against the Pandava ranks. And smiling the while, (several warriors on thy side), with a large number of steeds consisting of the best of the Kamvoja breed as also of those born in the country of the Rivers, and of those belonging to Aratta and Mahi and Sindhu, and of those of Vanayu also that were white in hue, and lastly those of hilly countries, surrounded (the Pandava army).
